How do faith, beauty and architecture come together in one of the world’s most extraordinary churches? Christopher Gunty speaks with architect Mauricio Cortés Sierra, one of the lead designers at Barcelona’s Sagrada Familia. He shares how Antoni Gaudí’s original vision continues to shape the basilica more than 140 years after construction began, including the recent completion of the Tower of Jesus Christ – the highest point in the church’s history. From the “Bible in stone” carved on the exterior to the awe‑inspiring light and space inside, this conversation reveals why Sagrada Familia is a powerful place of prayer and evangelization for believers and visitors alike.
